CLN-418 Study on Subjects With Advanced Solid Tumors

Phase 1
Completed
Conditions
Advanced Solid Tumor
Interventions
Registration Number
NCT05306444
Lead Sponsor
Harbour BioMed US, Inc.
Brief Summary

Study to evaluate the safety and tolerability of the study drug CLN-418, to determine the maximum tolerated dose and/or recommended Phase 2 study dose of CLN-418.

Detailed Description

This is a study to evaluate the safety and tolerability of the study drug CLN-418, and to determine the maximum tolerated dose and/or recommended Phase 2 study dose of CLN-418.

The study will also look at the anti-tumor activity, pharmacokinetics and immunogenicity of CLN-418.The study consists of 2 parts. In Part 1, patients are enrolled into different cohort doses in order to identify the appropriate recommended phase 2 dose (RP2D) or maximum tolerated dose (MTD). In Part 2, participants with metastatic / unresectable Non small cell lung cancer (NSCLC), Triple Negative Breast Cancer (TNBC) will receive the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) established in Part 1 of the study. In Part 1 and Part 2, participants will be administered treatment every 3 weeks.

Primary Outcome Measures
NameTimeMethod
Proportion of subjects with dose-limiting toxicity (DLT)From Day 1 until day 21

Number of subjects who experienced DLT events during 21 days after first administration of CLN-418, divided by the number of DLT evaluable Subjects

Secondary Outcome Measures
NameTimeMethod
Adverse events (AEs) according to Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0From signing of Informed Consent Form (ICF) till 84 days after last dose

Number of participants with Adverse Events (including vital signs, physical examinations, and abnormal laboratory parameters).

Objective response rate, defined as the proportion of subjects with best overall response of complete response (CR) or partial response (PR) per RECIST 1.1From time of consent until the first documented disease progression, unacceptable toxicity, withdrawal of consent, lack of treatment benefits, death or study termination whichever comes first, assessed up to 12 months

Proportion of subjects with best overall response of complete response (CR) or partial response (PR) per RECIST 1.1

Disease control rateFrom time of consent until the first documented disease progression, unacceptable toxicity, withdrawal of consent, lack of treatment benefits, death or study termination whichever comes first, assessed up to 12 months.

The proportion of subjects with a best overall response of Complete Response (CR), Partial Response (PR), or stable disease (SD).

Maximal tumor shrinkageFrom time of consent until the first documented disease progression, unacceptable toxicity, withdrawal of consent, lack of treatment benefits, death or study termination whichever comes first, assessed up to 12 months

The greatest tumor shrinkage achieved at any follow-up assessment

Pharmacokinetics Analysis - Time DeviationUp to 84 days post last dose

Reporting time deviation data of CLN-418

Duration of responseFrom time of consent until the first documented disease progression, unacceptable toxicity, withdrawal of consent, lack of treatment benefits, death or study termination whichever comes first, assessed up to 12 months

The time interval from first occurrence of a documented objective response to the time of disease progression as determined by the Investigator using RECIST 1.1 or death from any cause, whichever comes first.

Duration of disease controlFrom time of consent until the first documented disease progression, unacceptable toxicity, withdrawal of consent, lack of treatment benefits, death or study termination whichever comes first, assessed up to 12 months.

The time from the date of start of treatment to the date of disease progression or death for subjects who had CR or PR or SD during treatment
